Detailed Description
The invention will be further explained with reference to the following figures and specific examples:
as shown in fig. 1 to 4, an automatic yarn clearing device for a ring spun yarn spindle comprises a fixing frame 1 and a cutting assembly 2, wherein the fixing frame 1 is fixed on a spindle disc 3 and rotates synchronously with the spindle disc 3, the fixing frame 1 is in an inverted horn shape, a plurality of arc-shaped through holes 101 are uniformly arranged at the bottom of the fixing frame 1 in the circumferential direction, a plurality of cutting assemblies 2 are horizontally arranged at the upper part of the inner wall of the fixing frame 1, the cutting assemblies 2 are uniformly arranged around a spindle rod 4 in the circumferential direction, the cutting assemblies 2 comprise a supporting rod 201, the cross section of the supporting rod 201 is in an L shape, the end part of the horizontal section of the supporting rod 201 is connected to the inner wall of the fixing frame 1, a sliding groove is arranged inside the horizontal section of the supporting rod 201, a spring 202 is arranged in the sliding groove, the end part of the spring 202 is connected with, the upper end of the knife rest 203 is connected with a blade 204, the blade 204 is arc-shaped, and the blade 204 is movably connected with the knife rest 203.
When the utility model is used, the utility model is fixed on the spindle disk 3 by the staff, when the spindle starts to rotate, the fixing frame 1 rotates along with the spindle, the cutting component 2 arranged on the fixing frame 1 rotates along with the spindle, the knife rest 203 extrudes the spring 202 under the action of centrifugal force, the rotating speed of the spindle gradually becomes faster, the centrifugal force applied to the knife rest 203 gradually becomes larger, when the centrifugal force applied to the knife rest 203 is larger than the spring force of the spring 202, the knife rest 203 moves towards the side wall of the fixing frame 1 along the sliding groove in the supporting rod 201, the knife rest 203 is far away from the spindle rod 4, and the blade 204 can not cut the waste yarn wound at the bottom of the spindle;
when doffing operation is needed, the rotating speed of the spindle is gradually reduced, the centrifugal force is reduced along with the reduction of the spindle speed, when the centrifugal force applied to the knife rest 203 is insufficient to overcome the spring force of the spring 202, the spring force of the spring 202 enables the knife rest 203 to move towards the center of the fixed frame 1 along the sliding groove in the supporting rod 201, when the knife rest 203 reaches the vertical section of the supporting rod 201, the vertical section of the supporting rod 201 blocks the knife rest 203, the blade 204 arranged on the knife rest 203 contacts waste yarn wound at the bottom of the spindle rod, the waste yarn is cut off by the arc-shaped blade 204 in the rotating process, the cut waste yarn is thrown out of the fixed frame 1 along the arc-shaped through hole 101 at the bottom of the fixed frame 1 under the combined action of the centrifugal force; after the doffing operation is finished, the steps are repeated, so that the ring spun yarn spindle can automatically clear yarn once in the doffing process, manual operation is not needed, and the purposes of reducing the labor intensity of workers and improving the production efficiency are achieved.
The above-mentioned embodiments are merely preferred embodiments of the present invention, and not intended to limit the scope of the present invention, so that equivalent changes or modifications made by the structure, features and principles of the present invention should be included in the claims of the present invention.
